--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
If you are involved with the development of this application, could you verify
that it never uses a 32-bit color buffer with a 16-bit depth buffer, or a
16-bit color buffer with a 24-bit depth buffer? (That's RGBA8 + Z16 or RGB565 +
Z24.) Those combinations, while perfectly legal in GL, are not actually
supported by the hardware, and the driver "works around it" by just disabling
depth, which results in broken rendering (but at least no hangs...).

Another random thing to try: set NV30_SWTNL=1 in the environment - that will
make the tnl go through a software path

Lastly, please ensure you're using a semi-recent mesa...
